They can form some idea of what they are getting. If they buy a ton of fresh manure in November, they get 12¾ lbs. of nitrogen, and 30¾ lbs. of soluble mineral matter. If they buy a ton of the same manure that has been kept under cover until February, they get, nitrogen, 15 lbs.; soluble minerals, 42½ lbs. In April, they get, nitrogen, 23¾ lbs.; soluble minerals, 67½ lbs. In August, they get, nitrogen, 25½ lbs.; soluble minerals, 61 lbs. In November, when the manure is over one year old, they get, in a ton, nitrogen, 30¼ lbs.; soluble minerals, 88½ lbs. When manure has not been exposed, it is clear that a purchaser can afford to pay considerably more for a ton of rotted manure than for a ton of fresh manure. But waiving this point for the present, let us see how the matter stands with the farmer who makes and uses the manure. What does he gain by keeping and fermenting the manure under cover?
